Capsule optoacoustic endoscopy for esophageal imaging [PDF]
Journal of Biophotonics, 2019 AbstractDetection and monitoring of esophageal cancer severity require an imaging technique sensitive enough to detect early pathological changes in the esophagus and capable of analyzing the esophagus over 360 °in a non‐invasive manner. Optoacoustic endoscopy (COE) has been shown to resolve superficial vascular structure of the esophageal lumen in ...
